Comment 3 for bug 1012211

It works for me.
What NM version do you use?

Make sure "Use this connection only for resources on its networks" is not checked in the editor (IPv4 Settings, Routes...).

Would you, please, collect more information for us?
1. your connections data
nmcli -f connection,ipv4 con l id "your ethernet connection name"
nmcli -f connection,ipv4 con l id "your Wi-Fi connection name"

'never-default' option should be 'no'.

2. /var/log/messages
